Homemade Pistachio Paste Recipe | Like a cross between pistachio butter and marzipan, this thick and flavorful pistachio paste can be used on its own as a spread or as a base for colorful pistachio desserts. The mellow sweetness of this thick and flavorful pistachio paste will stand on its own when spread over toast or stuffed between layers of cake, but it can also work to flavor other desserts, as well. #pistachio#cake#baking
